Does having the A/C on while driving waste gas?

i don't know, but i do know that it kills the acceleration in some cars. I took Nature Boy's pink cadillac out for a spin....ok....i stole it cuz he was forcing me to go to another "leather man" party and i feared for my orifices. well anyway, as Nature chased after me with his friends Big Willy and Leather Larry, i noticed i could hardly outrun their morbidly obese asses when i realized the AC was on. once i turned it off, i high taled it out of the city. That's the last time i ever believe you Nature Boy when you tell me, "no, Freak, we're going to this supermodel party with all these chics from Maxim. yeah, sure, whatever.
 
Here's a tip: If you are driving on the freeway, its better to leave your windows closed and run the air conditioner. But if your driving in stop and go traffic leave the windows open and the air conditioner off.
 
The AC unit is an accessory that uses additional fuel and takes away from the power to the engine in a car. It creates heat by making the engine work harder so if you aren't moving a whole lot and the air isn't circulating to cool the radiator, you can put a strain in some older cars. Newer cars are designed much more efficiently and actually, some are built with two radiators like the entire Nissan line-up.
 
I have a older car, 94 Nissan Sentra and my I think my AC has been making my engine act screwy on really humid days. It even stalls. I'm trying to figure if it's the for sure ac and if it is what the hell is going on?

here in the heat and humidity core of the south, a/c is mandatory if u don't want to get somewhere sopping wet. the a/c works fine in my car, a cop copy mercury, does not overheat it or tax the engine.
 
I ALWAYS HAVE THE WINDOWS DOWN, NEVER USE AC.

ONLY TIME I USE AC IS WHEN I AM ALL DRESSED UP TO GO SOMEWHERE (JOB INTERVIEW, FANCY DINNER) AND DON'T WANT TO GET MY HAIR ALL FUCKED.
 
I don't give a fuck about speed, horsepower or acceleration.

I just want to be able to go to some mexican chicks house out in Norwalk in the middle of the day, stay cool, and not waste gas.
 
I always use the AC....didnt think it hurt the car that badly..mines a 94 Altima GXE
 
I don't think that "waste" is the right word at all. Does it use additional gas? Yes. Is it a "waste" of gas? Hell no.

My air conditioner keeps me comfortable. When I put on cologne, I still smell like cologne when I get out of the car. My back does not stick to the leather seats. My hair stays combed. I don't breathe exhaust fumes. Passengers in my car are comfortable. It is worth every penny of "wasted" gas.

When I drive with my windows down, I smell like shit when I get out. My hair is blown all over my head. It's still hot as shit, after all I'm just circulating hot air through my car. My back sticks to the leather. I choke on exhaust fumes and roast when at a stoplight. On the plus side, I get another 1.5 miles per gallon. I'll stick with my AC.
 
Yes it does.
In fact, driving with the defrost on in most cars wastes just as much gas. Most cars direct defrost through the AC compressor.

NFG
 
The drag co-efficient in most modern cars is probably not that great. (I mean unless you dirve at insane speeds) Especially if you have those little window visor/guard thingies.

The compressor in the AC pulls a significant amount of power from the engine, thus wasting gas.

You'd feel differently if you lived where I do! Today it's going to be 109 degrees and sunny. AC everywhere is a must unless you're floating in a pool.
 
Unless you drive a dump truck why would it matter?

Gas is around $1.40 a gallon
The average person drives 250 miles a week
The average vehicle (what a stupid word, vehicle) gets around 20 mpg.

So you will be buying about 12 gallons a week. If gas mileage is cut by 10% (a giant estimate, i am sure), you would spend an extra $1.50 a week on gas.
 
i have sold otherwise good cars b/c the a/c didn't get cold enough for me or the a/c broke.

nawlinz in the summer has temperature and humidity in the mid to high 90's. a/c is needed about 9 months out of the year.

also, i sweat like a some kinda farm aminal.:(

a/c has been perfected on american and japanese cars since the early 70's. (german, french and itlaian cars, that's a whole 'nother story!!) unless you are a bigger tightwad than even my father EVER was, use it and enjoy it!!!!!!!!

this thread could have been just answered with "conservation of energy"

as for what Nordstrum says here - I wholeheartedly agree. I have a friend that will drive around for 15 mins looking for the cheapest gas out there, that is usually about 3 cents difference in price. my car holds 15 gallons, which means he "saved" $.45 by driving around and wasting more gas.
fucking fuckers.

then there was a rental van place that I used once when I moved. there was no gas station anywhere near it, and you had to return it full or else there was a stupid fine (like $25 and then $5 for every gallon of gas after that - they really raped everyone).
so you couldn't drive to the place and then hope there was a place to top it off nearby. so you had to fill up elsewhere, but the trucks waste enough gas that by the time you get to the place, they are no longer full again. so they top it off to ensure nobody else will be able to fill it either and they fine you.
fucking fuckers.
 
I love to drive with the AC on and the wondows open.

I also love when it's cold to have the heat on and have the windows cracked.

It's these types of traits that make me irresistable to women and feared by my enemies.

that reminds me of the fine auto my dad/stepmom had for a bit while I was in high school. it was a '77 buick LeSabre. the combination of the exhaust emptying into the cabin, and the heater needing to be on all the time (esp in the summer) due to a faulty radiator - well, that just made it one pleasurable ride.
the other brilliant feature of said vehicle was its incredible lack of power. I'm not sure what was the exact problem, but you could never drive over 30mph in the thing, and when "accelerating" in it... you could easily be passed by elderly women using walkers.
it was baby blue with a scattered assortment of rust and brown primer.

not everyone gets to drive the car of their dreams.

I always drive with my window open, except when the fricking rain comes in, with the A/C on in the summer -- the heater on in the winter. I like to hear what's going on outside. As far as power goes, I don't have to worry about it with a 7.3 L. V-8. I don't consider it wasting gas. I'm using a bit more diesel fuel, but why not have the comfort; and this truck gets almost twice the mileage my previous gasoline-powered truck got with a similar-sized engine.

Uses more gas? yes.:(

But it is a necessity here in the south.:bawling: :bawling:

Amen to that. I actually try to drive without the air conditioner, but can only stand it for maybe about 5 min. The humidity down here is absolutely ridiculous and it makes me sweat like crazy....even just walking from my apt. to my car.
 
Hot chicks always have to have the AC on. Otherwise your car would overheat.

And in a similar note, hot chicks always have to leave the dome light on so that everyone can enjoy their looks.
